3 Claims.

This invention relates to a machine for the production of ornamented leather and other materials.

An object of this invention is to provide a machine whereby a sheet of fabric or imitation leather having a cemented surface may be ornamented with raised lineal designs on its normally exposed surface and then cemented into unitary relation with a lower layer of fabric having a l0 cemented surface.

Another object of this invention is to provide a machine whereby a plurality of cords may be secured between a two-ply fabric so as to ornament the upper layer with raised lineal designs known as cording.

Another object of this invention is to provide a machine having twoco-acting rollers and means for bringing upper and lower layers of fabric and interposed cords between said rollers, and to 2O rotate the rollers and cause the cords to be impressed into one of the layers of fabric in parallel relation and in predetermined parallel designs.

Another object of this invention is to provide a machine having two co-acting rollers, one of which has a plurality of wave-like parallel grooves and a wave-like cam at one end, and to provide control means whereby the wave-like cam causes corresponding wave-like motion of a plurality of cord holding members.

With the above and other objects in view, the invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the accompanying drawings and pointed out in the claims which form part of this specication.

Reference will now be had to the drawings, wherein like numerals of reference designate corresponding parts throughout the several views, in which:

Figure 1 is a cross-sectional view of the machine, the section being taken as on line I-l in Figure 3.

Figure 2 is a fragmentary sectional view, the section being taken as on line 2-2 in Figure 1.

Figure 3 is a plan view of the machine.

Figure 4 is an enlarged fragmentary portion of the cam end of the machine.

Figure 5 is fragmentary sectional view of the two rollers and showing a cord in the process of being impressed into a layer of fabric and uniting the two layers into unitary relation.

Figure 6 is an enlarged fragmentary longitudinal sectional view showing a plurality of cord holding members in operative position.

Figure 7 is a fragmentary sectional view of a cord holding member, showing a cord tensioning arrangement.

Figure 8 is a plan View of a portion of fabric which has been ornamented with raised lineal designs visible on its normally exposed surface 5 and known as cording.

Figure 9 is an enlarged cross-sectional View of the corded fabric, the section being taken as on line 9 9 in Figure 8.

In the illustrated embodiment of the invention 10 the numeral I0 indicates a machine for ornamenting the leather and other materials and comprises an upper roller II having a plurality of grooves I2, I2, formed in parallel and wavelike relation in its outer surface. At one `end of 15 the roller II and coaxially therewith, there has been .secured ra cam I3 having a wave-like formation like the grooves I2 but facing in the opposite direction.

Mounted below the roller II and in parallel 20 relation therewith is a roller I4 without any grooves in its outer surface. The rollers II and I4 have been rotatably mounted in bearings I5 and I6. A control arm I1 has beenmounted on a pivot I8 secured in `an arm I9. The arm I9 25 extends from the outer face of the bearing I6 and may be secured to said bearing by means of screws 20. At the free end of the arm I9 is a roller 2I mounted on a pin 22. The roller 2| i'lts in the wave-like groove 23 of the cam I3 30 and when the cam is rotated it causes the control arm Il to vibrate.

Slidably mounted in apertures 24 and 25 in the bearings I5 and I6 is a bar 26 carrying a plurality of cord holding members 21, 21, ar- 35 ranged in parallel relation to each other and spaced apart so as to be adapted to aline with the grooves I2, I2, in the roller II.

At one end of the bar 26 is a pin 28 in engagement with an elongated aperture 29 at the lower 40 end. of the control arm Il. It will thus be seen that motion of the control arm at the cam end will cause motion in an opposite direction of the bar 26 and the cord holding members 21.

As shown in Figure 2, `a gear 53 has been se- 45 cured to the shaft 54 on which the roller II is mounted. A gear 30 has been secured to the shaft 3l on which the roller I4 is mounted. The gears 53 and 30 are in intermeshing relation and cause the rollers to rotate in opposite directions. 50

A drive gear 32 in intermeshing relation with the gear 30 has been mounted on a shaft 33 .and a belt 34 on a pulley 35 may be employed to drive the gear 32 and impart motion to the rollers II and I4. 55

Coil springs 36 have been mounted in the bearings I5 and I6 and bolts 31 serve for adjusting the tension of the springs and for bringing the rollers against each other by yielding pressure.

As shown in Figure 1, the cord holding members 21 are secured in the bar 26 by screws 38 and are preferably bent upwardly at one end. At the end adjacent the roller I I, the cord holding members 21 have upwardly pointing ngers 39 which engage the respective grooves I2. The members 2l have springs 46, best shown in Figure '7. The springs are slightly spaced apart to receive the cords .and serve to cause a tension on the cords 4I passing through apertures in the members 2'I.

As shown in Figures 1 and 5, an upper layer of fabric 43 and a lower layer of fabric 44 have been rolled between the rollers Il and I4. The finger 39 seating in one of the grooves I2, has pressed a lineal portion of the upper fabric into the groove I 2 so as to provide room for a cord 4I to enter therein. It is to be noted that the lower surface 45 of the upper layer of fabric 43 and the upper surface 46 of the lower layer of fabric 44 have a layer of cement or other uniting composition applied thereto and when the machine I0 is in operation, the two layers of fabric `are pressed together and grip the cords 4I therebetween. The cemented layers .are forced into engagement and are forcibly and adhesively united by the pressing rollers and form a composite cemented fabric having raised lineal designs. The ornamented fabric may then be cut up into narrow widths for belt making or for ladies hand bags or for other uses.

As shown in Figures 8 and 9, the composite fabric 41 made 0n the cording machine I8 shows raised lineal designs 48 visible on the normally exposed surface 49 of the said fabric.

As shown in Figure 4, apertures 50 and 5I in the bracket I9 and on opposite sides of the pivot I8 may be respectively used to receive the pivot I8 and reduce or increase the vibrations of the bar 26 and the cord holders 21 so as to permit the use of a roller Il having different wave-like designs of grooves than that shown in Figure 3 .and to permit fabrication of differently ornamented composite fabrics than that shown in Figures 8 and 9.

I claim:

1. A machine for ornamenting a composite fabric with raised lineal cording designs, comprising an upper roller having a plurality of grooves arranged in parallel and wave-like relation in its outer surface and having a wave-like Cam at one end, a lower roller mounted in adjacent parallel relation with the upper roller, means for bringing the two rollers against each other by yielding pressure, means for guiding a plurality of cords intermediate fabric layers and in alinement with said wave-like grooves, and means for positively rotating said rollers in opposite directions.

2. A machine for ornamenting a composite fabric with raised lineal cording designs, comprising a ro-ller having a plurality of grooves arranged in parallel and wave-like relation in its outer surface and having a wave-like cam at one end, a further roller mounted in adjacent parallel relation with said grooved roller, means for bringing the two rollers against each other by yieding pressure, means for guiding a plurality of cords intermediate fabric layers having cemented surfaces and in alinement with said wave-like grooves, and means for rotating said rollers in opposite directions.

3. An apparatus for forming raised lineal parallel cording designs in a two-ply fabric, comprising a pair of spring pressed rollers, means for guiding a plurality of cords to said rollers, means to supply each cord under an individual tension, means to arrange the cords in parallel relation, one of said rollers having a plurality of design grooves formed in parallel relation in its outer surface, means for actuating said cords to cause them to follow the path in .said design grooves, and means for rotating said rollers in opposite directions.
